Regression in wininet between 0.9.23 and 0.9.24 - wine-devel

20 Nov 2006


      Hi!
  I would like to report a regression in wininet.dll, causing Dreamcom Kubik
SMS to crash as follows:

Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x7e687b86).

I was doing "cvs bisect" in dlls/wininet and found that the problem lies
between .23 and .24 - from .24 on it crashes, .23 is still OK. So now
I'm using HEAD wine with .23 wininet and the program is happy.
